Gas-generator.



' Isfol, specification.

.. Q2l1e,invention relates to a base or lower ifor-,gas generators ofthe typeV in which a.1;evolv1ng ashV and elinker basin is pro- Xi'ded,inwhich the lower part of the-generator wall projects. In suchI gasgenera- .trs 'theautomatic stirring of the combustibleis carried .out bymeans of a suitably constructed revolving grate, fastened on the basinand the'automatic removal of the ash :andy.,clinkers'is carried out .bymeans of plates-*which are fixed on the immovable generator wall andproject i'nto the basin.

The. essential features of the present invention consists in theconstruction of the plates for removing the ashes and clinkers, 'in thatthe uanti yof residue to be removed is indepen ent o the speed at whichthe basin and the grate fastened there on, revolve. Further thegenerator wall is so constructed, that an part of the interior of thelower part o .t e furnace is easily accessible. This is attained in thatall or a part of the plates lixed on the outside of the generator wallare provided with holes and are made adjustable. Further the generatorwall is constructed in several sections, one or more of which arearranged, so that they can be removed, the others however being fixed.

In the accompanying drawings: Figure 1 shows a View of the lower part''of the4 as generator, part being shown in section, 2 shows a plan ofthe lower part, and Fig. 3 shows a special form of construction of theplatesand the holes in the same.

The bottom of the generator wall is conveniently made of cast iron, andof cylindrical form. lIt consists of the ri 'd or Vfixed segments 1,which are rovided with bracket feet 2 in the nature o flying buttresses,and the removable segments 3. .The segments 3 are connected in anysuitable way with the segments 1. For instance, all segments mabeprovided with lateral flanges 4, whic can be held together by meansofbolts 5. The bracket feet 2 serve for bearing the wholel of thegenerator wall. Every two rigidsegments 1"areoonnected at the top iSpecification of Letters Patent'.

by means of a carrier, which serves for supporting the wall of thegenerator 6 in case one ofb the segments 3 is taken away. -In the formofconstruction shown a ring 7 is arranged' for this purpose, which liesover i all segments 1 and 3. i

8 is the plate, which is fastened on the outside of the generator wallfor removing the larger clinkers and coarser ashes. This plate isprovided with holes 9, so thatthe smaller clinkers and ashes can fallthrough, and remain in the revolving basin 10. If their removal, isdesirable or necessary then thesecond plate 11 is irovided. rlhis platehas no holes and can that it may project any desirable de th in the ashbasin 10. This plate can a so be removed, when this should be necessaryfor According to Fig. 2 the plate 8 may be constructed' in lattice form.But it can also as shown in Fig. 3 be constructed in the form of agrate. The holes 9 can moreover be made larger or smaller according tothe einders, and adapted to the same.

The basin or tray 10, which bears the grate 14 constructed. in suitablemanner, is 4driven by the usual cog' mechanism 15, or by any suitabledevice. r( )n the grate 14, a. lateral projection 16 in the form of ascraper may be preferably arranged for the purpose to prevent thesettling ofj the slag or elinker on the wall of the generator 6.

By means of the plate 8 'the larger clink ers, einders and coarserpieces of ash are taken out from the bottom of the tray 10, without toomuch of the ashes being removed. vWhen too much residue is' removed theburning material, from which the gas is being produced, and the freshcombustible e adjusted in height by means of the slot 12 and the bolts13, so

' 90 The ash and clinker basin can in the wellfall down too quickly, sothat an insutlicient yield is produced. The removal ofthe fine ash takesplace as required by means of the plate 11.

By employing a whole plate for removing the dross as was usual hitherto,the basin and with it the grate had to be rotated very slowly, sinceotherwise too much dross would be removed., This caused aninsulicientstirring of the combustible, so that this drawback is alsoremoved by the construction of the new lower part.

I claim: 1. lIn a lower part for gas generators consisting of singlefixed segments, removable'v segments of s aid wall, a bracket foot4 oneach fixed segment, means for .binding the removable segments to thefixed segments,

a rotatable ash and clinker tray the bottom oi said wall projecting'into said tray, means for automatically removing the residue from thecombustible, a grate fixed rigidly' on ,said tray, said grate projectinginto the in-v terior of the generator, and means for rotatthe grate,subsi'aning said tray and with it tially as set forth.

2. In alower part forgas generators, the

' .combination of acylindrical Wall, consistlngof singleixed segments,removable segments of said Wall, a lbracket foot onfeach v fixedsegment, means for binding theremovable segments to the fixed segments,a rotatable ash. and clinker. tray,'said generator .wall projectingvinto' said tray, an oblique plate. fixedon the outer circumference ofthe said wall, said plate vbeing providedt with holes, a second obliquelate, said second l plate being adjustable an removable on the outercircumference of the said wall, rigidly fixed on saidrotatable tra grateprojecting into the interior of 't e gen, erator, and means for ro'tatnsaid tray' and with it the grate, substantially as set f0lth. y 'I I 3.In a lower partfor gas generators the combinationof a cylindrical wall',said cylin- I drical wall consisting of. fixed segmentaand removablesegments, means for supporting' the Wall of the generator when therenierable segments are taken away, a bracket foot on each fixedsegment, 'mean-s for binding. the removable segments to thefixed f1agratev. i
